In the NDK circuit analysis, we mount a crystal unit on the customer's circuit board to check the matching with the crystal unit and propose appropriate conditions.

"If the matching is not appropriate, it may cause unexpected problems even in the market, such as non-oscillation, frequency shift, and startup failure. In order to avoid such problems and achieve stable oscillation, NDK has established a system that can propose the most appropriate matching."

As a result of the circuit analysis conducted so far, more than 70% of cases have been proposed some changes. If necessary, we will propose a change in the specifications of the crystal unit, the IC to be used, or the circuit constant.
